Design And Implementation Of Project Information Management System Based On SOA

With the rapid development of Enterprise information, there exits some IT application systems in one enterprise, cause of different construction time,realization technology and support platform, the systems above can't work together and can't achieve the purpose of function reuse, thus, it leads to the problem of resource waste and efficiency fall. On the other hand, the enterprise has ceaseless development and operation desire changes continuously, traditional enterprise IT application system, now, can't make prompt actions about the change of operation in time. Therefore, at present, it becomes a hot issue that seeks a blue print which can make the different architecture systems send information to each other, reuse the exiting function efficiently and do some swift response.SOA (Service-oriented Architecture) is the new generation design of enterprise IT application system construction. The enterprise now can get rid of technology-oriented solution and respond to the development and change of business service, cause of SOA. The advantages of SOA are that, it can reuse and combine the existing application to generate the new application service, provide the enterprise better flexibility to construct the application, so that, the enterprise can obtain better expansibility and reusability.Thesis does some research about the theory and technology of SOA at first, achieves in-depth understand about service and architecture module of SOA. It gives the detailed system requirement analysis and analyses the operation flow of process management subsystem. Then, puts forward the whole function architecture of the application system based on requirement analysis, and stresses the function architecture of process management subsystem. The thesis applies SOA into application system, improves on the traditional 3 layer software architecture, and achieves logistic layer architecture of project information management system based on SOA. At last, it researches the implement strategy of each layer and brings forward the specific implement. It is the keyword of the project information management based on SOA that the pick-up, design and implementation of the service-layer. Thesis demonstrates the process of service's public and transfer, using the implement of subtask service as an example.Thesis demonstrates better extensibility and reusability of the system which adopts SOA, and obtains a kind of sofeware architecture model based on SOA. So, it provides good adoptable sofeware architecture for other kind of information management system, this kind of model can accelerate the development of the new function module and adapt the change of market desire, make up the shortage of the traditional enterprise IT application system greatly.
